The Yakima Kayak Stacker carries river or recreational kayaks vertically with coated steel posts. Quickly tie off boats using the versatile arrow top hook. The Kayak Stacker is quick and easy to install onto both round and square crossbars.

This kayak holder is excellent. I carry 2 kayaks at a time and it could easily carry 4. I have only used it on my Audi A4, but it will work on any vehicle. I think it's really a 2 person job to load the kayaks on, but maybe with 1 kayak, one person could load it. It's great and quiet.

The stacker is functional and definitely gets the job done with the least impact on your wallet. The only problem is, when loading any kayaks (1-4), it basically requires the help of a friend to hold the kayak(s) while strapping them down... otherwise they slide and fall over. Once they're strapped in, you're good to go and it's all gravy. If you will be carrying 2-4 boats regularly, this is the way to go. But for me, I usually only carry 1-2. If I could do it again, I would spend the money and go with two sets of Hullraisers.

Can't beat the simplicity of this system. It easily allows for 1 to 4 whitewater kayaks on my 58 inch Cross Bars. Once I got my tying system down, I am able to drive knowing that the Boats will be there once I get to the put in.
